Software Quality Assurance
With 15+ years of experience, I find bugs before your customers do – covering functionality, security, and cross-device compatibility.
About me
As an experienced Software QA Engineer based in Zurich, I'm perfectly positioned to bring your website, app or API to a high standard – free from obvious and hidden defects. I guide your product through a series of systematic and thorough tests so it performs flawlessly at every release.
Software quality assurance is the one step in product development you cannot afford to skip – imagine the checkout process fails at the crucial moment.
Raised in Hamburg, I have been living in Zurich since 2022. I speak fluent German, English and Spanish and am available on-site in Switzerland and remotely.

Testing on real mobile devices under various network conditions for both iOS and Android.
Leveraging AI to support and extend your test strategy for faster and more comprehensive results.
Automated tests reduce manual effort and enable continuous quality assurance within the CI/CD pipeline.
